SHEET-GUIDE ADJUSTMENT.

Application filed August 24, 1921.

To all whom it may concern:

Be it known that I, J osnrn It. BLAINE, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in a Sheet-GuideAdjustment, of which the following is a specification.

In my Patent No. 1,367,229 I disclose sheet guide adjustable meanswhereby the gauges during the operation of the press can be adjusted tosecure accurate register. The present invention is an improvement uponthe arrangement disclosed by said patent One object of the invention isto simplify and improve sheet guide adjustment means whereby the actionthereof is more direct and positive than heretofore has been the case.

Another object to provide simple sheet guide adjustment means adapted tomeet the various requirements for successful commercial use.

These and other objects are accomplished by means of the arrangementshown on the accompanying sheet of drawings, in which Figure 1 is a planview of a side registering and adjusting mechanism embodying theinvention; and

Figure 2 .is a view of the same in side elevation with the revolvingparts displaced 90 from the position shown in Figure 1.

The various novel features of the invention will be a giparent from thefollowing description and drawings, and will be particularly pointed outin the appended claims.

Referring to the figures of the drawings it will be noted that I havedisclosed my invention in connection with a printing press including animpression cylinder 10 equipped with the usual grippers 11. Adjacent thecylinder 10 and in parallel relation thereto is a suitably mounted shaft12 driven at a speed corresponding to that of the shaft of theimpression cylinder.

In the patent hereinabove referred to I disclosed both front and sideregister means, while my present invention relates to side registermeans and more particularly means for adjusting the same while the pressis in operation.

For side registering sheet material there is keyed to the shaft 12 aside gauge arm 13 Serial No. 494,994.

having an extending boss 1 1. A collar 15 is loosely mounted upon theboss 1 1 and held in stationary position by means of an arm 16, one endof which embraces a supporting shaft 17. This collar 15 is provided witha cam 18 in one plane and another cam 19 in a different plane. The sidegauge arm 13 carries a side gauge 20 the position of which isadjustabletransversely of the press and longitudinally of the shaft 12 by means tobe described hereinafter in detail.

As appreciated, if the sheet material were not registered properly itwould be very inconvenient to stop the press and then adjust theregistering mechanism and then set the press in motion for a trialregistration and, then possibly stop the press again forfurtheradjustment. By means of the arrangement here shown the side registermeans may be accurately adjusted while the press is in operation.

In connection with adjusting the position of the side gauge arm 13 andits side gauge member 20, it will be noted that the outer end of thecollar 15 is provided with threads 21 and that said collar 15 is heldlongitudinally to the extending boss 14- of the side gauge arm 13 by anysuitable means such as an end plate 22 and screws 23 whereby there is norelative endwise movement between the collar 15 or more particularlywith its threaded portion 21 and the gauge arm 13. 'lhreadedonto thethreaded portion 21 of the collar 15 is a cap 2%, the internal threads25 of which engage the threaded portion 21 of the collar 15. Theopposite end of the cap 21 has an inturned annular portion 26 which isloosely received within a groove 2? of a clamp 28 secured to therotating shaft 12 by a bolt 29.

Let it be assumed that the side gauge 20 needs adjustment longitudinallyof the rotating shaft 12 for correcting registering conditions. Toaccomplish this adjustment the cap 2 1 normally stationary, which remains in the same relative position with respect to the clamp 28, may beturned either forward or backward with respect to the threaded portion21 of the collar 15 whereupon the side gauge arm 13 with its side gaugeplate 20 and also the arm 16 and all parts associated therewith may bemoved longitudinally with respect to the shaf t 12 for correcting sideregistering eoiulilions.

It will be unde stood that the side regis ter arm 13 and the partsattached thereto move forwardly with a sheet of paper for frontregistering the sheet, as described in said patent, and rotates with theshaft 12.

i he clamp 28 also rotates with the shaft 12,

but the remaining parts of the mechanism, including the collar 15 andcap 21-, remain stationary. Normally when the side gauge men'iber hasbeen accurately adjusted the adjusting cap 24-. is locked in adjustedposition by a set screw 30 which is threaded through a bracket Bl formedintegrally with the arm 16.

In connection with the operation of other parts of the mechanism it willbe noted that transversely slidable within the gauge arm 13 there is ashoe 32 carrying a roller 33 which works within an oblique slot l-l-l ofan angle lever 35, 36, the opposite end of which lever has a roller 37arranged to travel upon the *am 18. The other end o i the shoe 32opposite the roller 2-33 has pivoted thereto at 38 an arm 39 connectedby means of a rod. l0 to av link ll pivoted at the shoe which link tl isextended to form a flipper The rod 10 is surrounded by a. con'ipressionspring at the tension of which is adjustable by means of a knurled nut15. A coiled spring 46 much stiller than spring 4 lholds the stop +1? ofthe arm 39 against the shoe 32. The angle lever 35, b6 is fulcrumed tothe gauge arm 13 upon a pivot 48, and similarly pivoted to said arm at49 is an angle lever 50, 51, the arm 51 of which is provided with aroller 52 arranged to ride upon the cam 19, while the opposite arm 50 ofsaid lever has an offset portion provided with an inclined face 53adapted to engage the arm 39 to open and close the flipper l3.

In use the flipper 4; is normally closed, being held in this position bythe tension of springs "H: and 46. its the sheet advanced approximatelyto the front gauge, not shown, for front registering, the cam rollerrides upon the cam 19. opening the flipper l to allow the side edge ofthe sheet to pans and to offer no resistance to the action of the frontregister. The front register having been obtained the roller rides offthe cam 19 closing the flipper 43 upon the sheet 5 at the side thereof.Shortly thereafter the roller 37 rides upon the cam 18, bringing theoblique slot 3% to bear through the roller 33 upon the shoe 32, drawingthe sheet 54; to the left, as shown in Figure 1, against a side gaugemember 20, the flipper sliding upon the sheet during the further lateralmovement of the flipper and shoe after the side registration of thesheet.

At the moment the grippers 11 close on the sheet, the flipper 43 stillhas hold of the sheet and during the nex of travel of the cylinder 10the flipper slips off the sheet and allows it to pass freely to theimpression cylinder. The flipper then remains closed until the nextcycle starts. After the sheet is taken the roller 37 rides off of thehigh part of the cam 18 bringing the shoe 32 back to a startingposition.

It is my intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

I claim:
